Air fryer

Abstract

The present invention relates to manufacturing of kitchen appliances, and particularly to air fryer, comprising fryer body, liner, frying basket provided within the liner, electrical heating tube arranged above the frying basket and fan located above the heating tube. Side wall of the frying basket is thin plate and bottom of the frying basket is grid. Air channel is provided between the liner and the frying basket. Swirl guide cylinder is provided externally at the bottom of the frying basket and is connected with the side wall of the frying basket. Air inlets for forming rotary air flow are opened on the bottom of the swirl guide cylinder. The air inlets divert the air flow in a same direction and form a swirl. With such configuration, the frying basket is simple in structure, the liner is easy to manufacture and clean, and the frying basket is better supported.

What is claimed is: 
     
       1. An air fryer, comprising a fryer body ( 1 ), a liner ( 2 ), a frying basket ( 3 ) provided within the liner ( 2 ), an electrical heating tube ( 4 ) arranged above the frying basket ( 3 ) and a fan ( 5 ) located above the heating tube ( 4 ), wherein a side wall of the frying basket ( 3 ) is a thin plate and a bottom of the frying basket is a grid, and wherein an air channel ( 6 ) is provided between the liner ( 2 ) and the frying basket ( 3 ), characterized in that, a swirl guide cylinder is provided externally at the bottom of the frying basket ( 3 ) and is connected with the side wall of the frying basket, and air inlets ( 8 ) arranged evenly in a same direction and oriented clockwise or counter-clockwise are opened on a bottom plate ( 7 ) of the swirl guide cylinder; wherein the air inlets ( 8 ) are through holes in the cylinder; one side of the air inlets ( 8 ) being bent in a direction in which air flows to form guide plates, thus diverting the air flow in a same direction and forming a swirl; the bottom plate ( 7 ) of the swirl guide cylinder is connected with the side wall of the frying basket ( 3 ) via a connecting wall ( 70 ); and the overall flow area of the air inlets ( 8 ) on the guide cylinder is less than the flow area of the air channel ( 6 ). 
     
     
       2. The air fryer according to  claim 1 , characterized in that, the bottom plate ( 7 ) of the swirl guide cylinder is connected hermetically with the side wall of the frying basket ( 3 ) via the connecting wall ( 70 ), and supporting pillars ( 71 ) are arranged downward from the connecting wall ( 70 ) and are supported on a bottom wall of the liner ( 2 ). 
     
     
       3. The air fryer according to  claim 2 , characterized in that, another air inlet ( 72 ) is arranged in the center of the bottom plate ( 7 ) of the swirl guide cylinder. 
     
     
       4. The air fryer according to  claim 1 , characterized in that, another air inlet ( 72 ) is arranged in the center of the bottom plate ( 7 ) of the swirl guide cylinder.
